I used to be able to play Minecraft at 60-80 fps and video settings on max. I added shaders and it became very laggy and slow, so I took off the shaders and Minecraft started having 1-8 fps. I don't know what happened. I freed up space by deleting unused apps, removing everything in the temp folders, stopping apps from running in the background, uninstalling and reinstalling Minecraft, but nothing worked. I am a complete noob about computer stuff, so if I need to tell anything about my computer please let me know.
